| Abstract: | The definition of effective flange width was introduced,and the difference between it and the flange calculation width in the mid-span of beam were compared.The provisions about effective flange width in some representative codes of other countries were given and discussed.Some relative research in experiments and FEA simulation was described.Furthermore,in order to get a more resonable calculation formula of the effective flange width to consider the favorable effect of monolithic slab for the flexural capacity of beam end,the main influence factors of effective flange width were analyzed. |

| Keywords: | reinforced concrete frame monolithical slab effective flange width overstrength |
